udev-toradex-rules: colibri-imx7: Fix watchdog symlinks creation
Fix these unwanted behaviors:
- With kernel >= v6.3 /dev/colibri-watchdog-som and /dev/colibri-watchdog
are missing. Driver init sequence changes, the KERNEL label changes
from watchdog to watchdog1 and relevant rule that create the symlinks
stops matching.
- With kernel < v6.3 /dev/colibri-watchdog-som and /dev/colibri-watchdog-soc
are pointing to the same device, respectively /dev/watchdog0 (miscdev)
and /dev/watchdog (cdev) using the same watchdog device
(the SoM rn5t618 watchdog). Instead, it is expected that
/dev/colibri-watchdog-soc links to the SoC imx2-wdt watchdog device.
These are the current two configurations:
< v6.3:
/dev/colibri-watchdog -> watchdog0 (rn5t618)
/dev/colibri-watchdog-soc -> watchdog1 (imx2-wdt)
/dev/colibri-watchdog-som -> watchdog0 (rn5t618)
>= v6.3:
/dev/colibri-watchdog -> watchdog1 (rn5t618)
/dev/colibri-watchdog-soc -> watchdog0 (imx2-wdt)
/dev/colibri-watchdog-som -> watchdog1 (rn5t618)
